LPP 40 Description

The pressure test pump LR-Cal LPP 40 is used to generate pressure and vacuum for checking, adjusting and calibrating mechanical and electronic pressure measuring instruments by comparative measurements. These pressure tests may be carried out in laboratories, workshop or on site at the measuring point.

If the instrument to be tested and a sufficiently accurate reference measuring instrument are connected up to the test pump, the same pressure is applied to the two measuring instruments when the pressure test pump LR-Cal LPP 40 is operated. By comparing the two measure valuses at random pressure values, the accuracy can be verified or the instrument under test can be adjusted.

Despite its compact dimensions, the pressure test pump LR-Cal LPP 40 is easy to operate and allows for exact generation of the required test pressures; a change-over switch enables the generation of vacuum as well. The LR-Cal LPP 40 is fitted with a fine adjustment valve for generation of high pressure and a precise adjustment of pressures.

The reference instrument is screwd directly on the top of the pump and the unit under test is connected by means of the connection tube incorporating an adapter 1/4" BSP female thread (freely rotating), contained in the scope of delivery.
